LO'CK FOR BlCYCLE-LANTERNS.

SPECIFICATION forming part of Letters Patent No. 530,384, dated December 4, 1894.

Application filed June 18, 1894.

To all whom it may concern.-

Be it known that LWALLACE A. BLAKESLEE, a citizen of the United States, residing at Bridgeport, in the countyrof Fairfield and State of Connecticut, have invented certain new and useful Improvements in Looks for Bicycle-Lanterns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to produce a lock especially adapted as a means of securing bicycle lanterns to the usual brackets upon the machines by which they are car ried; it being essential in a device of this class that it be simple and inexpensive to produce, strong and practically impossible to get out of repair, and so constructed as to lock the lantern firmly and securely in place but permit its ready removal by the holder of the key.

With these ends in view I have devised the novel lock of whichthe following description in connection with the accompanying drawings is a specification, numbers being used to designate the several parts.

Figure 1 is a side elevation of my novel lock; Fig. 2, a section on the line w a; in Fig. 3 5 Fig. 3, a section on the line .y y in Fig. 4; Fig. 4, a plan view; and Fig. 5 is a view partly in section of the threaded rod, hub and key detached.

1 denotes a sleeveof ordinary construction which receives the lamp bracket, not shown, upon the bicycle and 2 the eyes to which the usual spring arms carrying the lantern are pivoted. As the lantern itself and the bracket upon thebicycle for-m no portion of my present invention I have not deemed them to require illustration. Within the sleeve is a plate 3 WhlGhiS moved forward to clamp the bracket by means of toggle levers 4 and 5, said levers being pivoted to the back of the plate which is provided with anear 6 for this purpose, a pin 7 passing through levers 4 and 5 and through the ear. I have shown two levers 4 and two levers 5 although but a single lever 4. and a single lever-5 may be used if Serlal No. 514,937. (NomodeL) preferred, the special details'of construction 50 not being of the essence of my invention. The other ends, of levers 5 are pivoted to a block 9 which is threaded to receive a rod 10, correspondingly threaded. At the outer end of this red is a head 11 provided with sockets 12 to receive lugs upon key 13. The operative parts of the lock are inclosed in a suitable case 14 which is preferably made integral with the sleeve. Below the case is a tube 15 the lower end of which is partly closed and is provided with an opening 16 shaped to correspond with the head of the key. Head 11 is held against other than rotary motion by closing the metal of the tube about it as clearly shown in Fig. 3, so that rotation of the head and threaded rod will move the block up or down and by means of the toggle levers will force plate 3 against the lantern bracket on the bicycle to lock the lantern in place, or if the rod is rotated in the opposite direction move it backward therefrom so that the lantern may be removed.

Having thus described 1 my invention, I claim- 1. A-lock of the character described consisting essentially of a sleeve adapted to receive the lantern bracket on a bicycle, a plate within said sleeve adapted to clamp the bracket, toggle levers pivoted to said plate and suitable means for operating said levers to move the plate toward or from the bracket.

2. A look of the character described con-- sisting of a sleeve to receive the lantern bracket on a bicycle, a plate within said sleeve adapted to clamp the bracket, toggle lovers 4 and 5 pivoted to said plate, a fixed pin to which the other ends of levers dare pivoted, block 9 to which the other ends of levers 5 are pivoted and a threaded rod engaging said block by which the latteris moved up or down to cause the plate to clamp or release the bracket.

3. A look of the character described consisting of a sleeve to receive the lantern bracket on a bicycle, a plate within said sleeve adapted to clamp the bracket, toggle levers 4L and 5 pivoted to said plate, a fixed pin to which the other ends of levers 4: are pivoted,

a block 9 to which the other ends of levers 5 In testimony whereof I affix mysignatu're in are pivoted, a threadeg rod engaging said presence of two witnesses. block and having a hea provided with sock- *1 e'ts to receive a key and a tube through which WALLACE BLAKEbLEE' 5 the key is passed and the metal of which is Witnesses:

closed about the head to prevent other than WM. A. LEONARD, rotary motion. NEAL F. CLARKE.
